i* PUMP.

To @ZZ/whom t may concern#A I Be it known that I, JOHN T. S. BROWN, Jr.,a citizen of the United States, residing at Prospect, county ofJefferson, andi State of Kentucky, have invented a certain new anduseful lmprovement in Pumps, ofwhic'h the following is a speciication.-

This invention yrelates to improvements 'in pumps with particularreference tO'thatcla-Ss known as tube or deep well 'pumps. j-

An obj ect is the provisionofa pump which will deliver a constantstreamv of water', thereby conserving the energy delivered tov the pump.v

A further objectl is'to produce a pump of` the class described whichwill be economical in construction, efficient in operation and du-`rable in service. A Y

With'the foregoing andy other objects in view, the invention consistsofthenovel ar-.

rangement and construction of parts, ill'ustrated in the accompanying"drawing,Which V forms apart of this specification, wherein is" set forthan embodiment of the invention,' but it isto be understoodt-hat suchchanges and modifications maybe resorted't'oxas come within scope of theclaimsl appendedl here-l unto. -V

Referring to the drawing whereinlike reference characters designate`similar parts f in the several views: Figurel, isa, Centrala verticalIsection, with portionsbrokenawayA and parts in elevation, yshowing theplunger near the completion of its downward stroke;

Fig. 2, a view similar to Fig. l, showing.. the plunger'near thecompletion of its upward travel; Fig. 3, a transverse section on lineX-X of Fig. 2; Fig. l-a perspective of the guide ring; Fig. 5,ajpl'anofthelsidel valve spring.

Referring to the drawing, the reference characters -A-, -B--,. and;`--C- desigf nate respectively three portionsor sections# of the pump,z'. e. a working'` barrel, aV valve chamber, and a dischargetubewhichkare se-- cured together at their points .ofconiectionV in anyof the usual wayslnownl to the, art.' The working barrel, is preferablycon-- speeiacation of Letters Patent. Patentedrct. 19,1915..Y 'ilimination'ieafnovember 181914. seriai No. 872,700. Y

inlet 6i-.V Nithinv the working barrel is ai' hollow piston, or plunger,+7- providedv with a'plurality of 'pistonrings -8-, which is open at thebottom and closedlat the top by an arch 9%. `,ln the linterior of thepiston near the upper vend thereofis a septum flO; on the upper face ofwhich isl a ball valve y`-ll-- which prevents a vdownward flow of fluidthrough an opening 'f-12,-. The rise of thevalve is limited by lugs1B--l which extend inward from the archedl inclosure 9. Connected to theupper end of the plunger andv in connection. withA thel interiorthereof, is a hollow piston rod ,-1e provided on its upper end' withsuitablemeans for the attachment thereto of a pump rod -15- whichextendsupward to a point o-f connection with asuitablejactuating force.In the side wallof thepiston rod, near the upperend thereof are alplurality of outletsLj-lG-, the totalare'a' of which is substantiallyequal to that of `the opening arranged in staggered relationship so yasnot to'w'eak'enthe rod.y kThe pumpfrod is pro-g' vided with sideextensions, or -wings 17- adapt'ed tolcont'act'withfthe sides ofthe dis-Q i l charge tube to prevent-side lash ofthe pump 'Y Y 85 Ac pluralityof inlet-openings, o-rports,

-18- are disposed about the'walls of the valve chamber. The flow of Huidtherethrough being controlledby valves ,--19-l each of which comprises abody portion 20.*` the face of which is contoured to conform tothecurvature 4ofy the walls of the chambei'and covered with a layer ofsuitabley pacl'ingmaterial such as leather secured thereto by metallicplates -22 The `val've'is carried on'the end of a exible member,@strap-23+. which is secured on an abutment, or. block, IThe valve `isconnected1 with" the. strap by means Aof vpins 25- which` extend'through elongated of-l connection ibyallowing restricted verticalvmovement of the valve while 7preventing any lateral movement'thereof,facilitates the' `proper ,S'e-tnelof the valve. Thetor' ofthe block 24'iscurved transversely, relative to the strap. 23 and the strap issecured thereon by means ofI bolts ,.and 28-', which eX-y tendJv throughthe walls of the chamber,

through the Vblock v 274, emerging therefrom on each side ofthe crown ofthe curved top, andV through perforations -29- inv the w ioo openings264 in the strap. u This method strap. A bolt which extends through VtheWalls of the chamber and through a. perforation -31- in thestrapprovides means .f

Vincrease the pressure exertedon the valve.

lt is to be understood that securing means will be used in connectionwith the bolts 27, 28, and 30, such as lock nuts, castellated nuts orother suitable means. Vlinmediately above the valves 19, an Vannularledge 32- extends inward from the wall of the chamber and forms a seatfor a valve. The ledge is spaced from the piston rod leaving a passage-38-- il sleeve -SSM' adapted to slide on the piston rod, has an annularenlargement S4-which rests on the upper face of the seat 32, and forms acutoff valve which closes the passage 38 during the downward stroke ofthe piston. A ring .-35- disposed about the piston rod, and spaced fromthe sides of the chamber by lateral arms, or lugs, -36-, is secured inposition by screws -37- and serves to limit the lift of the valve 34:and acts as a guide for the piston rod.

The operation ofr my improved pump is as follows: /Vhen the piston isVon the up stroke as illustrated in F ig. 2, the wateris drawn inthrough the foot valve filling the lower portion of the working chamber,and such of the water as is held in the chamber above the piston isforced up, its pressure serving to close the side inlet valves 19 and toraise the valve 34 on the piston rod, as shown, which operation opens upa free communication between the working chamberV and the discharge tubethrough the passage way -38-, it being obvious that during suchoperation the ball valve 11 will be forced back by the pressure of theWater Y valve 84 which is held closed by the weight to close the port l2in the upper end of the plungerv 7. -When however, the piston is forceddown as indicated in Fig. j l, the pressure will close the foot valveand force the water beneath the piston up therethrough lifting the ballvalve 1l and passing through the openings 1G, in the side of the pistonrod, into the discharge tube C. lt Will be Aobserved that yduring thisoperation the water inthe discharge tube will be prej vented fromentering the upper portiony of the working chamber by closing of theslide At thesame time the upper part of the chamber is refilled throughthe sidevalves 19. It will be seen that a continued flow of Water ismaintained through the discharge tube of the Water pressing downthereon.

during the operation of the pump. It is to be understood that the sideinlet valves may be placed in an integral extension of the workingchamber, instead of a separate ,sectionl as illustrated, vWithoutdeparting from the spirit of the invention. It will be observed that thearrangement illustrated permits of aready removal of parts forrepairsand adjustments.

. It is thought that the many advantages of my invention may be readilyunderstood from the` foregoing description,and that anyone skilled inthe art may make and use the same, and

l claim:

1. In a pump, a valve comprising a supporting block having a convex top,a resilient member extended from said block and secured thereon byadjustable attachment means positioned respectively on each side of theapex thereof, said resilient member having elongated openings near theouter ends thereof, and a valve connected to said member by 'means ofbolts passing through said openings.

3. In a pump the combination of a valve chamber having a port, a convexseat adjacent said port, a strap adjustably mounted on said convex seatand a valve carried by said strap and adaptedto open and close the portinthe valve chamber. Y

4. In a pumpthe combination of a valve chamberhaving a port, a convexseat adjacent said 'port, a flexible strapradjustably mounted on saidconvex seat and VaV valve carried by said strap and adapted to open andclose the port in the valve chamber.

5. ln a' pump the combination of a valve chamber having a port, a convexseat adi acent saidY port, a flexible strap mounted on said seat andadjustably secured thereon by fastening devices located at oppositesides of the crown of the convex seat and a valve carried by said strapand adapted to open and close the port in the valve chamber.
